Frequently Asked Questions

What SQL dialects are supported?
This formatter supports standard SQL syntax compatible with MySQL, PostgreSQL, SQLite, SQL Server, Oracle, and most other relational databases. It handles SELECT, INSERT, UPDATE, DELETE, CREATE TABLE, ALTER TABLE, DROP, JOIN, UNION, and subqueries.
Does formatting change the query behavior?
No. SQL formatting only adds whitespace, line breaks, and changes keyword casing. The query logic and execution results remain completely identical.
What does the Minify button do?
Minify removes all unnecessary whitespace, comments, and line breaks, compressing the SQL into a single line. This is useful for reducing payload size in API requests or configuration files.
Can I format SQL with subqueries?
Yes. The formatter handles nested subqueries, CTEs (WITH clauses), and complex JOIN conditions. Subqueries are properly indented for readability.
Is my SQL data safe?
Absolutely. All formatting happens entirely in your browser using JavaScript. No SQL data is sent to any server. Your queries remain completely private.

Additional FAQ

Why should I format my SQL?
Formatted SQL is easier to read, debug, and maintain. Well-formatted queries help you spot errors faster, improve code reviews, and are essential when sharing SQL with team members. This tool adds proper indentation and line breaks automatically.
Do different SQL dialects require different formatting?
While SQL syntax differs between MySQL, PostgreSQL, SQL Server, and Oracle, basic formatting principles (indentation, line breaks) are universal. This tool uses standard SQL formatting that works across all major dialects. Always test formatted queries in your specific database.
Can formatting help prevent SQL injection?
Formatting alone doesn't prevent SQL injection—it's purely visual. Always use parameterized queries and prepared statements to prevent injection attacks. See data validation tools for safety best practices.
